Introduction to Custodianship

Managing Information as a Resource

Information is one of the most important resources the ministry has. There is a significant cost to gathering and maintaining information, and the ministry cannot operate without it. Increasingly, information is being combined or updated by staff from many different areas, using different applications. Information from one program area is often relevant to many other program areas, and information from different program areas can and should be combined or integrated to be of maximum use. The integrity of this information is threatened unless proper care is taken. For these reasons, each discrete information subject (e.g. "Opening"; "Employee"; "Asset") and each application (e.g. "Timber Tenure Administration"; "Client Management") that is the responsibility of the ministry is assigned a single Custodian. The Custodian is responsible and accountable for managing corporate information or a corporate application as a vital resource on behalf of the ministry.

The integrity and sharing of information across the ministry, and the exploiting of information to the ministry's advantage via applications are the key focuses of the Custodian. Custodians provide leadership, and treat their scope of responsibility as the entire ministry, not only their own organizational area.

A Custodian enables cooperation, appropriate allocation of resources, and partnership throughout the ministry, and is accountable for determining the business information required by the ministry. This may involve influencing other program areas to convince them that proposed definitions and/or policies will meet the ministry's goals, and ensuring that conflicts between ministry business needs are successfully resolved.


Overview of General Responsibilities

Data Custodianship involves two main areas of responsibility:

Application Custodianship involves two main areas of responsibility:


Data Custodian

In the past, applications were developed on a departmental basis, but the increasing use of shared database technology has changed the nature of these systems. Today, ministry information is quickly becoming more and more integrated across all systems platforms. Because of this increased sharing, ways must be found to encourage the joint funding or sponsorship of information management across departmental, application, and program area boundaries.

A Data Custodian's responsibilities pertain to the creation and use of data for the purpose of enabling decision-making and providing information. At a detailed level the Data Custodian is concerned with information structures called entities and databases (see Definitions). These structures usually require some maintenance, improvements or enhancements, and updates over time.

Detailed Responsibilities (Data Custodian)

Data Custodians are responsible for the structure and content of information the ministry needs to conduct its business, within the context of the Data Custodian's business area. The Data Custodian's obligations include:

  1. Information management:
  2. Information sharing:

Application Custodian

An Application Custodian's responsibilities pertain to the building of automated applications for the purpose of processing routine transactions, and enabling information retrieval and the resultant decision-making by ministry staff. Applications often access information from many different subject areas, and at a programming level access data from databases. It is essential for application custodians to work with any custodians who control information in databases to which their application requires access.

Detailed Responsibilities

Application Custodians are responsible for ensuring that, within the scope of their application boundaries, the ministry's processing requirements are met through the accepted practice of multiple releases of an application over time. The Custodian's obligations include:

  1. Application development:
  2. Application management:

Steward

A sub-class of the Data Custodian is a Steward, who at the request of and on behalf of a Data Custodian, can ensure that a set of the Data Custodian's information is available, if that Data Custodian does not have the appropriate operational resources available to provide the necessary functions. The Steward chosen will likely be a Data Custodian for other program information (since by definition the Steward must have access to operational resources).

The Data Custodian remains fully responsible for the information with respect to the business, but can delegate technical or operational portions that may be better dealt with by other experts. In other words, the Data Custodian is responsible for specifying what information is recorded but might delegate the decision of how it is stored and retrieved to a Steward. The Data Custodian specifies the business use of the information including structure, format, content, and how the information relates to other business information. The Steward might then ensure that, for a particular operational platform, the integrity of the information meets the published standards. The Steward will have only limited responsibility for information content.

Detailed Responsibilities

The scope of each Steward's responsibilities depends on the particular arrangements made between the Steward and Data Custodian, however, Steward responsibilities will always be a subset of Data Custodian responsibilities. The primary purpose and responsibility of a Steward is:

The following list contains suggestions where identifying a Steward may assist custodians in managing their information resources. A Steward might assume some or all of the following obligations, depending on the needs, resources, and decisions of the Data Custodian:

The following table may help to describe the differing levels of responsibility between the Data Custodian and the Steward.

Data Custodian Steward
Defines data requirements to a standard specific level (information content) - retains responsibility for what business data is recorded. Processes data into the physical platform and manages the data thereafter from a technical perspective - might be responsible for how data is recorded.
Defines and publishes business specifications for spatial data requirements. Ensures the data entering the physical platform meets the published standards in terms of format (representational and positional), and limited content.
Defines and publishes business specifications for spatial data requirements. Assists in defining physical specifications for spatial data requirements where technical expertise is scarce and the Data Custodian does not have access to such expertise (e.g. where spatial/GIS data management is pushing the boundaries of available technology).
